Service bulletin L-SB-0177-09 Rev

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

When this condition occurs, Diagnostic Trouble Code (DTC) B1479 (Flow Sensor Circuit) may also be stored in the A/C system as either a Current or History DTC. A malfunctioning A/C compressor flow sensor may cause this condition.
